🏆 Our Recommendation
Walmart offered the lowest verified price in this comparison at $4.97 for 454 g. Real Canadian Superstore was $1.02 more at $5.99, while Costco Same-Day was $6.57. Walmart is our current pick, but its $4.97 price is promotional and may vary by location, so compare your local flyer before shopping.
🍁 Smart Shopping Tip
Butter freezes extremely well for several months without affecting quality. If you find a good sale, consider buying two or three blocks and freezing the extras. This can help reduce your grocery bill over time.
Frequently Asked Questions
Is Costco always the best place to buy butter?
Not always. Costco often offers excellent everyday value, but grocery stores such as Walmart or Real Canadian Superstore may occasionally have lower sale prices.
Should I buy salted or unsalted butter?
For everyday cooking and toast, salted butter is the most popular choice. If you bake frequently, unsalted butter gives you better control over the salt in recipes.
How long does butter last in the freezer?
Butter can typically be frozen for up to 12 months if kept well wrapped.
🍁 Great Canadian Finds Verdict
Best Overall Value: Walmart
Best for Families: Costco
Our Pick:
If we were buying a standard 454 g block today, we would choose Walmart while its $4.97 price is available. If that promotion ends, Real Canadian Superstore’s $5.99 No Name butter is the next-best verified option in this comparison.
